7 claims. (c1. 24a-'m' i convolutions thereof. This exible material isThis invention relates to a machine for coiling strip and particularlyrelatively wide metal strip having Ian vuncoated'. Such material lacksthe low frictional coeilicient of one that has been coated and istherefore quite difllcult to wind into tight coils. .For instance, tinplated strip may be relatively easily coiled becauseof its ratherslippery surface, while plain cold rolled strip is rather dillicult tocoil because of the friction between thesurfaces of successiveconvolutions. Consequently, one of the objects 'is to tightly coil plainmetal strip. f It is desirable to 'coll this strip on flanged spools,and' this presents a further di'iliculty in that the edges of thematerial tend to rub against the 'anges' and Abecome damaged. In view ofthis, another object is to coil metal strip, particularly 'rather widestrip, on flanged spools with out damaging its'edges by such rubbingcontact.

Other objects than the above may be inferred from the followingillustrative disclosure of the invention in a specinc form.

Referring to the drawing: v

Figure l is a top plan.

Figure 2 is a cross-section from the line II-II inFigure 1.

Figure 3 is'an end elevation. i

The above diagrammatically illustratethe in vention, an efort havingbeen made to include only the essentials needed for illustrativepurposes. A

This machine includes a anged spool 1 mounted on a spindle 2 driven lbya motor'B through a suitable gear reduction. This spool might besubstituted by aspindle if the strip is vnot to be vwound to include'theprotection of a flange. A table 4, having a convex surface, is arrangedat right angles to the axis of the spool 1 and has an. end swingingadjacent thereto.

The en'd of this table remote from the spool is pivoted on a shaft 5which also lI nounts a roller 6.l The strip is fed under this rolleronto the table and is thus held thereon. Theswinging end of the tablecarries'av woodclamping block 7 having a form matching that of thetables surface. This clamps the strip on the table and frictionallyprevents it' from running thereover too freely.` Preferably, the clampand table are covered with carpet or other soft material to preventundue scratching-of the strip.`

The swinging endofthetable4alsocarrles a length of canvas, leather,brass sheeting or other flexible 8 whichis suitablyflxe'd thereto andextends partially round the strip clamp '1.

' tially Vbalances it.-

The strip is fed beneath the roller 6 onto the table 4 and beneath theclamp '7. This causes it to assume acrowned shape which decreases itswidth sufficiently to withdraw its edges from any possible contactwiththe flanges of the spool, except where the strip being reeledtangentially, comes in contact with the convolutions of that portionalready reeled. The table 4. might obviously be concave and thesameeifect obtained. The clamp 7 is preferably held to the table bybolts 10 so that its frictional restraint of the strip may bevaried. P

The length of canvas 8 being beneath the strip separates apart of theouter or feeding convolution thereof from that coiled. This changes thefrictional coeilicient between the surfaces from sufciently to permitthe material being coiled to slide easiLv into position between thelrotating anges allowing the application of sufficient tension on thestrip to insure obtaining a tight coil.' The strip,- on sliding easilyinto position, eliminates the possibility of damaging the edges. Othermaterial might be substituted for the canvas provided it is relativelyflexible and 4can function to separate the feeding strip convolutionfrom thoseof the,coil and thus obtain the desired re- It will be seenthat a tight coil free of damaged edges results essentially from theconstant withdrawal of a strip of materialfrom beneath theoutermostconvolution. The length which the canvas 8 extends between thecircumferential surfaces of the strip's convolutions can be varied bythe operator to secure the best possible results.

As the convolutions on the spool 1 increase, the:

table ,4 will swing so that the strip is always subpreferableto'carpet`for surfacing the ltable 4 and Although n Snecma form of thisinvention has. been shown and described in accordance with the patentstatutes, it is not intended -to limit the 4scope of the inventionexactly thereto, except as denned in the following claims.

I claim: f 1. A machine vfor coiling strip including the combination ofa rotary carrien'means for turnstatic toslidng, 1111s reducing thefrictional effect;y

vranged between the feeding or outer convolution and the coiled onesthereof circumferential surfaces.

3. A machine for feeding 'strip -including the combination of a xedlypositioned rotary carrier, means for turning said carrier, a tablehaving a for a portion of their laterally curved surface and arranged ata right angle to the axis of said carrier with an end swinging adjacentthereto and means for holding the strip on said table for feeding ontosaid carrier.

4. A machine for coiling strip including the combination of a rotarycarrier, means for turning said carrier, a table having a laterallycurved surface and arranged at a right angle to the axis of said carrierwith an end swinging adjacent thereto, means for holding the strip onsaid table for feeding onto said carrier and a length of flexiblematerial of a Width substantially equal to that of the strip and fixedto the swinging end of said table beneath the feeding strip andterminating part way around the coil thereof.

5. A machine for coiling strip including ythe combination of a rotarycarrier, means for turning said carrier, a table having a laterallycurved 'carpeted surface and arranged at a yright angle to the axis ofsaid carrier with an end swinging adjacent thereto, means for holdingthe strip longitudinally on said table for feeding onto said carrier, acarpeted clamp on 'the swinging end of said table for applyingfrictional restraint to the feeding strip, and a length of flexiblematerial. of a Width substantially equal to that of the strip and xed tothe swinging end of said table beneath the feeding strip and terminatingpart way around the coil thereof.

6. The method of coiling metal strip on a spool or spindle consisting inturning the spool or spindle while tensionally feeding the stripthereonto and keeping the outer of feeding strip convolution separatedfrom the coiled ones for a portion of their mutually opposedcircumferential surfaces.

7. A machine for coiling strip, including the combination of a iiangedrotary carrier, means for turning said carrier and means for feedingstrip substantially tangentially onto said carrier while bending it to asufficiently distorted form to cause its edges to clear the anges ofthelatter, the last named means being constructed and arranged to effectsaid bending solely by the application of bending forces laterally tothe faces of said strip while leaving the latters edges entirely free tobe drawn together only because of said distorted form resulting fromsaid bending.
